The Interstate 41 expansion project, set to continue until 2030, will bring significant modifications to the highway infrastructure in Wisconsin. In 2025, construction efforts will concentrate on two key segments: between State 96 and Lynndale Drive in Grand Chute, and between Outagamie County JJ and Miners Way near Wrightstown. This initiative aims to enhance traffic flow and safety by expanding lanes and rebuilding interchanges. The Wisconsin Department of Transportation has outlined detailed road closures and changes that residents can expect throughout the year.
In addition to lane expansions and new collector-distributor roads, the project will introduce diverging diamond intersections at critical junctions. These innovative designs aim to streamline traffic movement and reduce congestion. Public meetings and online resources are available for those seeking more information about the project's impact and schedule.
Beginning in February 2025, several major road closures will take effect along Interstate 41. The affected areas include the stretch between State 96 and Lynndale Drive in Grand Chute, as well as the segment between Outagamie County JJ and Miners Way around Wrightstown. Drivers should anticipate significant changes to their usual routes.
Specifically, the Lynndale Drive overpass will be reduced to one lane in each direction during spring and summer. Meanwhile, the southbound exit ramp from I-41 to State 96 (Wisconsin Avenue) will remain closed from early in the year until summer. Further closures include the State 15 (Northland Avenue) bridge over I-41, which will be inaccessible from early in the year to fall. Additionally, Ballard Road bridges and ramps will experience closures from spring through late fall, impacting travel between I-41 and nearby streets. Other notable closures involve Capitol Drive, Holland Road, Vandenbroek Road, and the Outagamie County J bridge. For the Outagamie County JJ to Miners Way section, South County Line Road under I-41 will be shut down for two weeks in summer, while the Wrightstown Safety and Weight Enforcement Facility remains closed until summer 2026. Construction activities related to the Southbridge Road interchange in De Pere will also cause temporary closures of Mid Valley Drive and French Road/Southbridge Road.
The Interstate 41 expansion project plans to significantly upgrade the highway's infrastructure, focusing on enhancing capacity and safety. Key improvements include widening the interstate to six lanes over a 23-mile stretch and constructing collector-distributor roads to better manage local traffic. Rebuilding interchanges and overpasses is another crucial aspect of the project, with some overpasses being widened to accommodate pedestrians and cyclists.
One of the most transformative changes will be the introduction of diverging diamond intersections at Ballard Road and State 15. These unique designs operate similarly to one-way streets, eliminating the need for left turns into oncoming traffic. This modification promises to improve traffic flow and reduce accidents. The project also aims to support heavier vehicles and increased traffic volumes, ensuring smoother and safer travel for all users. Residents can stay informed about these developments through public meetings and the official project website, where updates and newsletters provide comprehensive details on the progress and impacts of the expansion.
